Detection, identification, and antibiotic treatments of bacterial contaminants from micropropagated strawberries

Creator:: Tanprasert, Piyarak
Abstract:: Bacterial contamination is one of the most important problems both in plant tissue culture research and commercial laboratories. Early detection of contaminants saves time, effort, and money. Strawberry runner explants were screened for contaminants during June to August, 1994 and 1995. Most contaminants found were bacterial rather than fungal. Bacterial...

Modification of phyllosphere environments to enhance establishment of Gliocladium roseum, an antagonist of Botrytis cinerea

Creator:: Bennett, Robert J. (Robert Joe), 1953-
Abstract:: Radial colony growth of three isolates of Gliocladium roseum and three isolates of Bottytis cinerea were measured on 1/4 strength potato dextrose agar amended with concentrations of NaHCO₃ ranging from 0-2% (w/v). Compared to the control, reductions in colony diameter of the B. cinerea isolates ranged from 60-79% and 73-89%...

Multiple pest suppression with cover crops in strawberry

Creator:: Datta, Braja Bandhu
Abstract:: The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...

Temperature-dependent development of strawberry root weevil Otiorhynchus ovatus (L.)

Creator:: Umble, Jon R.
Abstract:: The temperature-dependent development of pupae and adults of strawberry root weevil (SRW) Otiorhynchus ovatus (L.) was studied in strawberry (Fragaria x ananassa Duch. var. 'Totem'). The development of pupae and adults was investigated at constant temperatures from 3-33°C at 3°C intervals. Major emphasis was on the development of a weighted...

Partial characterization of the P4 pathotype of pea seedborne mosaic virus

Creator:: Kohnen, Paul D.
Abstract:: Biological, serological, and molecular characteristics of the P4 pathotype of pea seedborne mosaic potyvirus (PSbMV) were investigated. The characterization allowed P4 to be differentiated from other pathotypes of the same virus. P4 was distinguished from P1 on the basis of host symptomatology. It induced varied, but often distinctive symptoms in...

Irrigation and plant density effects on head rot and yield of broccoli

Creator:: Ludy, Robin L.
Abstract:: Effects of amount of applied water and frequency of irrigation on head rot and yield of three broccoli cultivars were evaluated in 1987 and 1988. Two irrigation frequencies were established with a line-source sprinkler system for 5.5 weeks during heading. The low-frequency experiment was watered once per week and the...

Assays to determine tolerance of cherry rootstock to bacterial canker caused by Pseudomonas syringae pv. syringae

Creator:: Krzesinska, Elzbieta Z.
Abstract:: Bacterial canker, caused by Pseudomonas syringae pv. syringae is recognized as one of the greatest limiting factors in cherry production in Oregon. Disease incidence may be decreased when susceptible cultivars are high-grafted onto tolerant/resistant rootstocks. This research was begun to develop a rapid screening method which could be used to...

White muscle and other selenium-responsive diseases of livestock

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Hansen, Donald, Hathaway, Ronald L., Oldfield, J. E., 1921-, and Pacific Northwest Cooperative Extension
Abstract:: Oregon State University researchers made a significant discovery in 1958. They found that the underlying cause of white muscle disease is a dietary deficiency of the trace element selenium (Se). There is a fairly clear-cut relationship between soil, plant, and animal factors. Certain soils, including some formed by volcanic action...
